Specific embodiment
Below with reference to specific example and attached drawing, the present invention will be further described.
As depicted in figs. 1 and 2, the present invention provides a kind of easy collapse hole soft stratum ultra-deep based on charge sleeve lower in drilling rod
Hole loading method, comprising the following steps:
Material needed for S1, preparation explosion；Including charge sleeve 4, powder stick 6, detonator 7, flexible padding, bus 8, water stemming material and Huang
Mud.
S2, using large through-hole drilling rod 2, be equipped with before drilling rod 2 center can open and close type drill bit 3, drill out blast hole 1 to design hole
It is deep, cleaning bottom of hole 3-5 minutes, drilling cuttings is discharged；The hole size of the drilling rod, which is subject to, can smoothly be inserted in charge sleeve；Described
Drill bit original state is closed type.Large through-hole drilling rod 2 and center can the drill bit 3 of open and close type be existing matured product, therefore it is unknown
Thin narration.
S3, drilling rod 2 and drill bit 3 are stayed in blast hole 1, and certain distance of dropping back, so that the bottom of drill bit 3 and blast hole 1
There are certain spaces between portion, unload the water swivel axis of 2 tail end of drilling rod.Left certain space can put down the fixed dress of elastic claw formula
5 are set, the present embodiment certain distance is 0.3-0.5m, preferably 0.5m.
S4, first 4 front end of charge sleeve is connected to the fixed device 5 of elastic claw formula, is sent into the drilling rod 2 together,
According to explosion design requirement charge material in first charge sleeve 4, then connects next charge sleeve 4 and be sent into the brill
The interior simultaneously charge material of bar 2, until charge sleeve 4 all connects simultaneously charge material.Specifically, the closely loading in charge sleeve 4
Powder stick 6 and detonator 7 simultaneously connect payment to a porter, bus 8, be then sequentially connected next charge sleeve 4 and be sent into large through-hole drilling rod 2
It is interior, at the same in charge sleeve 4 closely loading powder stick 6 and detonator 7 and connect payment to a porter, bus 8(according to explosion design determine medicine
Volume 6 and 7 dosage of detonator), the flexibility batten filling such as 6 surrounding wicker of powder stick is fixed.Bus 8 is led to outside blast hole 1.This implementation
In, charge sleeve 4 is threaded connection type fire-resistant antistatic pvc pipe, and the interior diameter through being greater than powder stick 6 of charge sleeve 4 is adjacent
It is threaded connection between charge sleeve 4.
S5, charge sleeve is sent to the drill bit of drilling rod bottom, suitably firmly to the charge sleeve 4 in drilling rod 2, opens drill bit
3 Centralizing fins 9, so that the fixed device 5 of elastic claw formula passes through drill bit 3 and reaches the certain space, the fixed device 5 of elastic claw formula is certainly
It is fixed on the dynamic hole wall opened elastic claw 10 and snap into blast hole 1；The firmly size suitably firmly is not to destroy powder charge set
It connection between pipe 4 and can open subject to the Centralizing fins 9 of drill bit 3.
S6, drilling rod 2 and drill bit 3 are slowly exited, charge sleeve 4 and the fixed device 5 of elastic claw formula are retained in blast hole 1.
S7, after moving back finishing drilling, water stemming material, yellow mud is sent into blast hole outer segment using tamper and is consolidated to blast hole sealing of hole.
The method of the present invention will can be led to greatly after the drilling of drill bit 3 to design hole depth of open and close type using large through-hole drilling rod 2 and center
Hole drilling rod 2 protects hole wall as temporary casing, from the inner hole tripping in charge sleeve 4 of drilling rod 2 and drill bit 3；Bullet before charge sleeve 4
The fixed device 5 of claw is automatically opened across elastic claw 10 after drill bit 3 to be snapped on the hole wall of blast hole 1, makes charge sleeve 4 when moving back brill
It is retained in blast hole 1 and completes powder charge.The method of the present invention efficiently solves the rock stratum that degree of consolidation is poor, intensity is low, weakness is frangible
Due to the unstabilitys such as blast hole collapsing, chip off-falling, necking down, deformation can not deep hole explosive problem, can smoothly realize that easy collapse hole is weak
Hundred meters of superdeep holes powder charges in rock stratum, improve the safety of deep hole explosive.Meanwhile this method simple process, it is easy to operate, have
Wide applicability.
Above embodiments are merely to illustrate design philosophy and feature of the invention, and its object is to make technology in the art
Personnel can understand the content of the present invention and implement it accordingly, and protection scope of the present invention is not limited to the above embodiments.So it is all according to
It is within the scope of the present invention according to equivalent variations made by disclosed principle, mentality of designing or modification.
